Korte beschrijving Morfologie | Morfometrie

Dorsale stekels (totaal): 0; Dorsale zachte stralen (totaal): 6-9; Anale stekels 0; Anale zachte stralen: 8 - 11. Diagnosis: both males and females are readily distinguished from Rivulus cylindraceus by the presence of a dark lateral band situated longitudinally along the lateral line, extended from the posterior margin of the eye to the base of the caudal fin; dorsal fin slightly shifted to the caudal peduncle in relation to the origin of anal fin (1–3mm) when compared to Rivulus cylindraceus; frontal scalation pattern in Rivulus berovidesi sp. n. is d-type vs. e-type pattern in Rivulus cylindraceus (Ref. 101368).

Biologie     Verklarende woordenlijst (bv. epibenthic)

Inhabits small mountain streams with bottom substrate basically composed by stones, sand and dead leaves; no aquatic vegetation in the area (Ref. 101368).

Estimates based on models

Fylogenetische diversiteitsindex (Ref. 82804):  PD50 = 0.5010   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00977 (0.00315 - 0.03034), b=3.03 (2.78 - 3.28), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trofisch niveau (Ref. 69278):  3.2   ±0.4 se; based on size and trophs of closest relatives
Weerstandsvermogen (Ref. 120179):  Hoog, minimale populatieverdubbelingstijd minder dan 15 maanden (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
